I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hello, My company recently purchased a dual 4k setup for a work station. The setup is the following:2 ThinkVision P27 monitorsLenovo ThinkPad Thunderbolt 3 DockT570 (Type: 20HA) I setup the monitors and docking station yesterday and was able to power the displays using a X1 Carbon 5th gen (i5 model type: 20HQ) thru USB-C without issue. I have a user testing out the desk now with a T570. I'm able to get one monitor to funtion at 4K and the other is running at 1080p. If you check display settings I'm unable to increase the resolution to 4K. I've updated all drivers on the T570 including the display driver and thunderbolt docking station driver this morning and the system still fails to power dual 4K. I brought back the X1 I used previously and it powers the screens normally. I checked the specs of the T570 and its identical to the X1 as far as processor is concerned and the model page claims the USB-C port on the T570 can power dual 4K. What else can I try?

I bought a T570 running on Windows 10 with a resolution of 3840 x 2160. It works quite well for most applications like Chrome, Windows and Office apps. In others however the fonts and icons are almost unreadable tiny. I noticed many of them are Java-based or rather old.  I tried playing around with the scaling in the display settings of Windows. Setting it to 210 % improved the readability of the apps that were already OK, but it had no effect to the problematic apps.  Has anyone else the same problems?Is there any way I can adjust the scaling of these apps?

Hey so I recently purchased a systemboard replacement off of eBay. The 'Supervisor Password' was set. He found a different board to send to me to fix that problem. Thing is as far as i can tell its a T580 (01YR306) that he wants to send me. I have a T570 (02HL452) that I am replacing. Is this going to cause a problem like i think it might? My search results were limited when trying to get a full list of compatiable boards. And there is no way this supervisor password isnt some default setting? No other security features are enabled so I don't see why there would be a supervisor password set if nothign else is. I assume its from a company that just didnt remove it and all is legit just not usable for my situation. I mean i can boot into windows just fine. I didnt miss somethign about a default setting when the battery is removed for extended period of time though, did I? Thanks -James

(For those of you who have followed my previous threads, I've now ordered a T580 with 4k display). I'm looking for a T3 dock which can do the following on a T580. It would allow me to use just one cable to dock/undock it: 1) Attach a screen with a 2560x1440 resolution with 60Hz (digital connection)2) Attach a screen with a 1920x1200 resolution with 60Hz (digital or VGA connection)3) Full Ethernet port4) Charge the laptop (originally, it comes with a 45W power adaptor)5) Have at least 1 classic USB 3.0 port Unfortunately my budget is limited so that I can't go for the original Lenovo one. If there's a dock which can all the above except for attaching two screens, then this would be ok as well, for the time being (assuming I can run one screen via the dock, and the other screen directly from the HDMI of the T580). Then it would just be 2 cables for docking/undocking...

Folks - Just wanted to share the early results of my experiment with adding a Thunderbolt 3 eGPU enclosure to my T570 laptop. I just got this up and running, but everything operates mostly as expected so far. The only negative items so far are that my Ultradock does not have a Thunderbolt 3 port, so I must connect the TB3 cable directly to the laptop.

Hi all, I have a Thinkpad T580 and a Thunderbolt 3 Dock Gen2. It worked fine until now.I updated the Dock Firmware, and everything worked. I updated the BIOS from 1.21 to 1.22, and Thunderbolt is not working anymore. Were I work we have many Lenovo Laptops and Docks. I tried another Dock, but the thunderbolt software does not show a connected device. I reflashed the 1.21 BIOS version, but thunderbolt stays broken. How could that happen?I even set the Thunderbolt Security to "no Security" in BIOS, thinking it might have broke security, but no, does not work. When I plug it into USB-C it works, of course. But this way I only have 10GBit/s for everything, not 40Gbit/s like with Thunderbolt. That means not all of my monitors do work and bandwidth is limited. Any ideas how to remedy the situation? Best, maybeapreacher

Hi there,  I've been experiencing issues with both Thinkpad T580's and 5th/6th Gen X1 Carbons. Basically any model that has USB-C/Thunberbolt connectivity.  I have had users report that their laptops either connected to their docking station or power adaptor  do not charge. Windows reports "Plugged in, Not charging", and power drops. The dock does not appear to work, external screens, network etc.  When disconnected from the power source or dock, the orange power light on the left site where the USB-C connector is stays on. This is the light that comes on when charging. When the laptop is shut down, the same orange light stays on.  The work around I've found is to go into the BIOS, Power settings, Disconnect the internal battery. (External battery needs to be removed for the T series). After selecting this, the laptop powers off and the orange charging light goes out. Once reconnected to a power source, the laptop will power on, work with the dock and properly charge.  I have encountered this on multiple T580's and multiple X1 Carbons. I've attempted to run the System Update utility (excellent app btw) and made sure BIOS and Thunderbolt firmware etc is up to date, yet the issue still persists. Logging into the BIOS and disconnecting the internal battery is not a viable solution.  Is there a solution for this, and are Lenovo aware of this issue?  Thanks,Adam

 My T580 suddenly one day stopped reading my external USB-C hard drive, I tried updating the drivers and several other suggested repairs with none of them working. The power light on the drive would come on but the computer didn't read it, verified with a second drive and they both work on my other computers. Looking at the timeline, I realized that this happened while the computer was still within it's warranty period, but I was busy and just let the problem go. Then two weeks later the computer just shut down on me and after letting it sit with the lid closed for a while, it was able to restart and I got a warning message at the BIOS screen that "The Power Adapter is of lower wattage than the one supplied with the machine" or something along those lines. Once booted up I was able to see that battery nuber one was fully depleted to 2% and the 2nd battery was at 99%, it then shut down on me again. I ordered a replacement power adapter to test and got the same message and the same symptoms, the computer would basically trickle charge at a rate slower than it consumed power, at this point I finally called customer service and started a repair ticket, this is when they told me that the computer was three weeks out of warranty....I send it in and a week later recieve a repair estimate of $589 to replace the whole motherboard. I called right back and complained that this computer was having problems before the warranty was up and was simply told it was out of warran...

Because they are 30 inch monitors!

You can get 2560 x 1600 resolution in a smaller monitor, but to get that resolution in a 30 inch monitor requires billions more pixels (OK- slight exaggeration. Maybe millions)

I have T570 and two same "thinkpad ultra dock" docking stations - one at the office and the other at home- with two monitors connected on each of them (DP & HDMI). At the office, I close the lid (2 screens) and at home I keep it opened (3-screen setup). A while ago it started flickering / blanking external monitors on *both* of them. Sometimes, when computer is left locked for some time (sleep is disabled!) external monitors are blanked and I can only revive them by removing + attaching the laptop to the dock again. I tried firmware updates on dock, driver updates on windows / lenovo... nothing helps. Windows 10, latest updates. I find it weird that two docks would go bad almost simultaneously. What else can I try - it is driving me crazy as I cannot work normally (sometimes it blinks like every minute or so but other times it is OK for more than an hour)?

Hi, Goal : plug a T580 by one port to a multiple screen setup. I read that your nvidia geforce mx150 embedded T580 does support their optimus software, which smartly switch between the intel iGPU and the nvidia dGPU. What is unveiled nowhere is whether the mx150 can handle multiple monitors, but I guess so, since current intel iGPU can handle up to 2 additional monitors. Now what happens on linux distributions with DisplayLink devices (pluggable USB adapters to some video output, relying on an integrated cheap external GPU), is that their driver is such that the display can only be done through a non-nvidia GPU. As currently using the open-source Nouveau driver instead of the proprietary one leads to a crazy unstability with the DisplayLink devices. You gys have done a pretty good guide about optimus GPUs and multiple screens setups here : https://support.lenovo.com/gb/en/solutions/ht037605 . However it's out of date and doesn't speak about OS, I'm sure it'd be worth it to update it for your newest thinkpads. My final questions then are :- Do your docking stations use any driver / thirdparty hardware ?-- if yes,--- Are those drivers DisplayLink branded?---- if no,----- Are they linux compatible? ( https://www.lenovo.com/gb/en/accessories-and-monitors/top-tech/Thunderbolt-Dock-UK/p/40AC0135UK here is written 'OS independant', it'd be great if you could quickly give it a try with e.g an ubuntu bootable and any 2 other monitors ) In fact I woul...

Can a DP and USB-C on the dock be used for two 4k monitors? Is there any combination of ports that would allow the dock to support two 4ks?

Hey Lenovo Team, I have a T580 laptop connected to a Lenovo ThinkPad Ultra Pro docking station. There are two monitors connected via Displayport and a third (which is actually a projector) via HDMI. I read that if you were to use three external monitors on a docking station, that you need to get an Ultra Pro Docking station, but I didn't know if that meant three not including the external display. As of now, I can't get the extended desktop to display on the projector, unless one of the other monitors or the built-in monitor on the laptop gets disabled. On the Intel Display software, I am only given three monitors that I can configure, even though there are FOUR on the pull down list. In the Windows Screen Resolution settings, you can see there are four monitors detected, but the fourth one, you can't do anything with and it says it's not active. The graphics drivers software, BIOS, and Ultra Pro Docking station firmware are all up-to-date. I tried configuring the other monitors' resolutions as requested on the support site for resolutions/refresh rates supported (they are all 1920x1080 @ 60 Hz) and yet I still can't get the fourth monitor to work. I'm not sure if there's a BIOS setting that needs changing or what I need to do to get all the monitors to work or if, in fact, you can't get the three external monitors plus the internal laptop monitor to work.Could someone provide some assistance or suggestions to get the monitors working? That would be appreciated!

I have a Lenovo T570 (Type 20JW, 20JX) Laptop (ThinkPad) and ThinkPad Basic Dock (40A00000WW).   I have a monitor plugged into the VGA connection on the docking station.  I have another monitor connected to my laptop with HDMI.  When the laptop is docked, the display will show on the laptop and the monitor connected to the dock.  The monitor connected via HDMI goes black.  When the laptop is off the dock, the HDMI monitor works.  Is there a way to get both monitors to work without having to buy a different docking station?  I know the ideal situation would be to get a different dock with 2 connections on it, but I was hoping not to have to pay for another dock.

Checking to see if anyone has had this issue. We have 5 T570 20JW, running the most current verison of Windows 10Pro and since Yesterday (9/18/17), whenever a user undocks their laptop and then redocks it the external monitors do not turn back on and Windows does not recognize the 2 displays either. The only way we have been able to get them to show back up is to either reseat one or both of the monitor cables from the dock or put the laptop into sleep mode and then wake it backup using the docking station power button. It's not the displaying drivers causing the issue, at least not directly as we have tried the most current and the last release and neither fix the issue and as I stated this just started on 9/18 and the most current drivers are a few months old now. My only guess is that it's one of the 5 lenovo updates that where installed yesterday or the latest bios update (See the attached picture). I haven't had the chance yet to uninstall each of the 5 updates because I will need to go download the last version of each of them first, but wanted to see if any one else has had this happen and to forwarn anyone that has one to be careful with the most current updates. Thanks, Joseph

Does the Thinkpad P51s support the Thinkpad Thunderbolt 3 Dock? I have the Thinkpad P51s with stock Windows 10 Pro and updated to latest drivers and Windows version and installed the latest Thinkpad Thunderbolt 3 Dock drivers. Attaching the Thunderbolt 3 Dock to the P51s as described in documentation, it charges the notebook, however, noting attached to the dock is recognized. I've tested with attaching USB flash drives, headphones, Ethernet, HDMI, and DP, but nothing is recognized nor are any warnings/errors displayed in Windows. While the Thinkpad Thunderbolt 3 Dock is listed as being compatible with the P51s and T570, the notebook order page does not list the Thunderbolt 3 Dock in any of the accessories lists. Lenovo Sales also confirmed that the Thunderbolt 3 Dock is fully compatible with the P51s.  However, I needed to purchase the Thunderbolt 3 Dock separately from the notebook order. What's going on? Has anybody successfully used the P51s or the T570 with the Thinkpad Thunderbolt 3 Dock? Or is this something I need to wait for full support via a future BIOS/driver update? Or perhaps my Thunderbolt 3 Dock is defective? Thanks,Boris

So I have a Precision 5510 laptop with Xeon processor, no 4K screen.  My question is about this thunderbolt dock TB16.  I have one HDMI out and was asked if I can make that work on 3 external monitors.  None are 4K.  Is that possible?  Can it function as extended desktop, not duplicated? And if so, is that 3 external plus laptop? Or is the laptop screen on of the 3?

I am trying to sovlve the problem of driving two 4 k monitors with my P50 W7 with a dock. Nvidia states it is a Lenovo issue. So I try the work around with a thunderbolt adpater.  I bought two. 1.StarTech.com Thunderbolt 3 to Dual Monitor DisplayPort Adapter - Thunderbolt to 2x DP Converter - 4K 60Hz The P50 will not recognize this.  I loaded the newest drivers and still no good. Does not recognize it.  I see that W10 has a brand new software release 9/26/16.   Where is the one for W7? 2.TechOrbits USB 3.1 Type C (USB-C & Thunderbolt 3 Port Compatible) to DisplayPort 4K UHD USB-C to DisplayPort AdapterThis one worked after some scary video episodes.  I used it last night.  Now no good. Something failed?   My device manager does not show a 3.1 usb. So when will Lenovo fix this so we can drive two external DisplayPorts? This is a real problem. Does anyone have a workaround for W7? ?03-04-2016 08:27 AM Had the same problem. Internally, BOTH ports on the dock are hooked up to a single GPU port, so all monitors are effectively limited by a single DisplayPort 1.2 bandwidth. You can run 4K monitors @ 30Hz though. Or get a Thunderbolt 3->DisplayPort adapter.

Hello, I'm trying to connect two external monitors (1920x1200) to my X1 Carbon 6th and only one of them actually works. The other one is displayed as a small square in Windows display settings. When I checked "Advanced display settings", I see all display adapters (3 total), but one of them shows up as "Display 3 isn't active.". I'm using a Thunderbolt 3 to dual displayport adapter (this one). Can anyone help me with this issue? Thanks!

Hi There, I'm having trouble with a Lenovo P52 with a Thinkpad Thunderbold 3 Dock. When I Conect my dock to my laptop it wil ask if i want to allow it. (It always asks strangely.

(Docks that work with other Lenovo laptops)-It works somtimes. once every 5-10 tries. But fail right after trying again.-No Faults in Lenovo center. Product information:Lenovo Vantage InfoLenovo Thinkpad Thunderbold 3 DockModel Number: DBB9003L1 I have updated the most drivers that would be needed for the thunderbolt & Lenovo but nothing seems to work. Is there anyone who has been batling this before or somone who could help me?

 Hello all, I am a solutions architect trying to solve an issue which I have never heard of before. Though others users are having this same issue, my experience has been different then what they have seen. First,The following are the Security options for Thunderbolt devices as per user guide

No Security: Allow Thunderbolt devices to be connected automatically.
User Authorization: Allow Thunderbolt devices to be connected after user authorization.
Secure Connect: Allow Thunderbolt devices to be connected with a saved key that has been approved by the user.
Display Port and USB: Allow only DisplayPort-compatible devices and USB devices to be connected. Thunderbolt devices are not allowed to be connectedI don't think this is entirely true or at least does not apply properly each time. My scenario:T480, T580, or Yoga x1 3rd genImaging with a standalone MDT environmentDevices come pre-configured from Lenovo with Thunderbolt 3 Security Options set to "User Authentication" Installing all the drivers in the latest SCCM driver packs that Lenovo offers - though the x1 3rd gen driver pack was missing on the site this morning. On some devices, this security option seems to do absolutely nothing. MDT uses the local "Administrator" account to perform post-OS items. I'd say about 75% of the devices reach their destination and the user logs in for the first time as a user, not an admin, and the dock functions properly; monitors/mice/keyboard/etc. work. 25% of ...

My office just upgrated to the the Zbooks with thunderbolt docking stations. Most of us have 2 monitors. Those of us with LG monitors can not connect both monitors using the Display ports or it locks up the docking station or notebook. If we connect one in the display port and one with VGA it will work. But the one in the display port drops from 1680X1050 to 1600 X 900. The one connected with VGA will have 1680 X 1050. Notebook will not let us put the display port any higher than 1600 X 900. This are the same monitors. On the old notebooks we had this was not a problem. Both were being run at 1680 X 1050. Please someone tell me what I need to do to get this to work. On the filp side some people have Bell monitors and this is not a problem with them. It is only with the LG monitors that we have this problem. The LGs are 2 years old.  The dells are over 5 years old.

I tried to ask on Reddit but it looks like nobody knows the answer. trying it here  where could I find a confirmation that the T470 with onboard HD 620 graphics can drive two 4K Dell P2415Q at 60Hz monitors when connected via Thunderbolt? PSREFs just say it can support up to 3 displays (which is cool, but at what resolution and what will be the refresh rate) and max resolution supported is 4K at 60Hz (again, great, but how many of them?)I was planning to use either the Startech's Thunderbolt 3 to Dual DisplayPort Adapter or Dell TB16 dock to connect the monitors, as Lenovo is not providing ways to connect two 4K monitors over the DisplayPortIdeally, I'd love to have a dock which can connect both monitors but as I understand current generation of mechanical docks does not allow to use two 4k monitors, I guess it has something to do with bandwidth of chips used for DP ports in the docks.

I have narrowed the issue down to a software issue.  I have tried resetting the dock, the computer, updated to the newest driver as well as even replacing the dock itself.  I had an extra and thought the dock ports might just be dead but the new dock doesnt work either.  I have also tried both ports on the PC in order to rule that out as well.  Does anyone have suggestions?  Thank you in advance!!

OOTB when I connected the Thunderbolt 3 dock to my X1 Yoga (3rd Gen), the monitors behaved correctly. I installed all available updates for the machine as per the Lenovo Companion App, this included some firmware upgrades the dock. When I came into the office this morning, the laptop would not switch from single monitor mode, and the screens connected to the dock are not detected. Steps I've taken:Checked for updates via the Lenovo siteInstalled a Thunderbolt 3 Firmware upgradeReinstalled the Intel Display DriverAttempted to install drivers directly from intel (failed. referred by error message to lenovo website)De-authorized & Re-authorized the dock via Thunderbolt SoftwareI feel like I've made a simple settings change that is preventing the dock from showing me the devices available. Anyone have any ideas?
